BEET-HARVESTER.

Specification of Letters Patent.-` Patented Sept. 29, 1914.

Application filed February 14, 1913. SerialNo. 748,408.

To all whom t may concern Be itknown that we, JEDAH Gr. VVEB'BER andCHARLES F. CARR, citizens of the United;

for elevating the beets and depositing them in a receptacle and fordischarging them inl piles on the ground for subsequent gather-` ing.

A further object of the invention isto simplify and improve the variousdetails of the machine.

With these and other ends in view which:

will readily appear as the nature of the invention is better understood,the same consists in the improved construction and novel arrangement andcombination of parts which will be hereinafter fully described andparticularly pointed out in the claims.

1n the accompanying drawings has been illustrated a simple and preferredform, of

the invention, it being, however, `understood that no limitationisnecessarily made to the precise structural details therein exhibited,but that changes, alterations and vmodifications within the scope of theclaims may be resorted to when desired.

In the drawings,-Figure 1 isa side elevation of a beet `harvesterconstructed in accordance with the invention. Fig. 2 is a longitudinalsectional view. Fig. 3 is a horizontal sectional view taken on the line343 in Fig. 1. Fig. 4 is a rear elevation. Fig.

5 is a transverse'sectional detail view taken on the line 5*-5 inFig. 1. Fig. 6 is a sectional detail view of the topper. Fig. 7 is adetail plan view of the lifting plowsand the rollers associatedtherewith.

Corresponding parts in the several figures are denoted by likecharacters of reference.` The main frame of the improved machine`includes side members 1 that converge forwardly and are connected attheir front ends with a center bar 2 which extends forwardly andconstitutes a tongue.

bers, as shown. The Vside bars of the frame are provided with boxes orbearing members 4 for the axle 5 on which the ground wheels A rear crossbai-j 3 connects the center bar with the side inem- 6 are mounted forrotation therewith, it. be-

ing understoodthat any well known form of a clutch may be used to permitthe ground wheels torotate independently of the axle.

Pivotally supported on the axle 5is a rear- `war'dly extending frame Fon which a shaft `7 is `supported for rotation, said shaft beingconnected with the axle so as to derive motion therefrom by intermeshingbevel gears 8, 9. The frame F is provided with dow-nwardly extendingbrackets 10 that are pivotally connected by pins or bolts'll-with the`side members 1Q, of a sub-frame G,said side members 12 convergingforwardly, as shown,

and the said sidemembers being connected witha forwardly extending arin13 that is pivotally connected with a bracket 14 eX- tending downwardlyfrom the center bar 2 of the main frame. which connects the arm 13 withthe bracket 14 is adjustable in any one of a plurality of perforationslinfthebracket 14, thus permitting the arml 13 which constitutesv thefront end ofthe sub-frame G to be vertically adjusted with respect, tothe main frame.

Thepinor bolt 15- The arm 13 is provided with a lkeeper 17 wherein isguided a shank 18 carrying at `its lower end the topper19, said toppercon- "sisting of a rectangular plate disposed obliquely with respect tothe frame of the machine and having uwardly curved front and rear edges20 and 21. Said plate isv also provided with arecess 22 disposed inparallel relation to the oblique front and rear edgesof the plate, thecuter or rearmost end of said recess opening through the side edge ofthe'topper plate. The rear edge wall of the recess `22 is bentdownwardly andy is beveled or'sharpened to'form a cutting edge E23, iitbeing understood that the topperlplate is made of steel properlytemperedlto en- 9 able it to holdal cuttingedge. The shank 18 carryingthetopper plate is freely movable in the keeper 17, and the topper platewill -drop by gravity to a ground engaging position. When in suchposition the upy turned front edge will enable it to ride over theVbeets, the tops of which will be crushed downby the weight of the plateand shank.

The cutting edge 23 will sever the "tops, which latter as the machineadvances `will slide laterally and rearwardly until they escape throughthe open end of the slot or recess, said discharging movement beingfacilitated by the upturned rear edge 21 of the topper plate, wherebythe severed tops For the Vpurpose of limiting the down ward movement ofthe topperv when the carryingframe is elevated, as will be hereinafterdescribed, the shank 18 is connected by a link 24 with a lug` 25 thatextends downwardly from the arm 13. r1his link, which alsoserves toreinforce the construction so as to avoid undue strain on the keeper 17kand the shank 18, is sufficiently loose to per- `mit the topper tooperate in the manner described The side members 1 2 of the sub-frame G`are provided with standards 26 carrying 'right and left plows 27 whichare sumjciently spaced apart to operate adjacent to the row of beets.ried by shanks .2Q/are also provided in ad- Vance of the plows. Thelcolters will servel to cutinc-isions in the soil adjacent to the beets,and the yplows will move the dirt away froinjthe sides of the row ofbeets, as will be `readily understood, the beets passing betweenl theplows in a rearward direction.

Bearings are provided in rear of the plows for a pair 'of rearwardlyconverging rollers 30, said bearings being associated with the sub-frameG; One of the rollers 30 is driven by a chain v31 direct from the shaft7, and

g the other rolleris driven by a chain 32 from a counter shaft 3 8 whichreceives motion from the main shaft 7 through the medium ofintermesljiing gears 34 so as tov be driven reversely` to, the saidshaft 7. One of the rollers will thus be driven clockwise and the otherroller counter-clockwise in such fashion asl to exercise a liftingaction on the beets engaged thereby, the beets being by the,4 action ofsaid` rollers gradually eX- `traeted from the ground, as will be readilyunderstood. The sub-frame G is equipped with l.guard'strips or members'constituting/a cage to. prevent the beet from being `lostsidewise. overthe rollers. Guard ineinbers 3.6, are also connected with the plowsextending rearwardly therefrom adjacent to` the rollers and exteriorlyof the latter to prevent saidv rollers from being clogged with dirt.

v lliivotally associated with one of therollers f 'i 30is the lowerl endof an elevator trunk or casing 37 supporting an endless carrie'r 38which` is guided over a pulley 3.9` which is supported for rotationabout the axis-of the roller. The elevator casing v37 is also connectedwith abracket 4:0. associated with the ,snub-frame. G.V -The rollercarryingshaft 41 tion.

Rotary colters 28 carover which the carrier 38 is guided at the upperend of the casing 37 is provided with a pulley L12 which is driven fromthe shaft 7 by means of a chain or band 4:3.

A rock shaft 44- which is supported for oscillation on the frame Ftransversely of the latter has an arm L15 carrying a receptacle 46 intowhich the beets discharged by the elevating carrier 38 are deposited;the rock shaft 4% has a lever L17, whereby it may be convenientlymanipulated for the purpose of dumping the contents of the receptaclee6. The lever 47 may be provided with a stop member 48 engaging asuitably arranged rack segment 41:9 for the purpose of supporting therock shaft and related parts including the receptacle 1G in adjustedposi- Pivoted on one of the side members of the main frame is a bellcrank B having an upwardly extending arm 5() constituting a handle; theother arm 51 of the bell crank is connected by a link 52 with the frameF, thereby enabling the. rear end of said frame to be verticallyadjusted by rocking said frame with respect to the axle on which it ispivotally mounted. The arm 5() of the bell crank may be provided with astop member engaging a suitably arranged segment rack 54 for the purposeof mailitaining the parts in position at various adjustinents.

1t will be seen that by manipulating the bell crank B, the frame F,together with the sub-frame G, may be adjusted vertically so as to movethe various operative parts of the device into or out of engagingposition with respect to the ground. .lt will be noted ythat while suchadjustment involves an independent movement of the sub-frame G withrespect to the frame F, the brackets 10 of the frame F with which theside ineinbers of the sub-frame are pivotally connected are placed orlocated in such close proximity to the transmission chains 31 and 32that said chains will not be subjected to undue tension when thesub-frame is lowered to an operative position, nor will said chains vbeliable to be displaced from the cogs of the sprockets engaged therebywhen the frame is raised or elevated. When the mavchine is drawn overthe ground.v the tops of the beets` will be removed by the topper, thecolters and the plows will remove the dirt from the sides of the beets,and the beets will be engaged by the lifting rollers, being `dischargedfrom said rollers on to the elevating carrier whereby they are depositedupon the receptacle 16 to be subsequently dumped on the ground in pilesconvenient for gathering.

The entire construction of the machine is simple and inexpensive, andthe machine will be found to be thoroughly eflicient for the purposes`foi which it is provided.

Having thus described the invention, what is claimed as new, is

l. ln a beet harvester, a wheel supported frame structure including amovably and adjustably supported sub-frame, colters and plows carried bythe sub-frame, said plows being spaced apart laterally, rearwardlyconverging driven rollers supported in rear of the plows, and guardmembers Constituting a cage between said rollers.

2. ln a beet harvester, a frame structure, right and left hand plowscarried thereby, rearwardly converging driven rollers in rear of theplows, guard members extending rearwardly vfrom the plows outside therollers, and guard members constituting a cage between and above therollers.
